Scales of Evolution & the Hardy Weinberg Flashcards
Large-scale big picture evolution?
Macroevolution
Phenotypic changes over time
Observations of Macroevolution?
Fossil Record
Speciation
Evolution where we can actively see the progress?
Microevolution
Allelic frequency changes over generations
T/F Microevolution leads to new species
FALSE
Microevolution is fueled by…..
Natural Selection
T/F INDIVIDUALS DO NOT/CANNOT EVOLVE
TRUE!!!!!!!!!!
Instead of looking at individuals we would look at the…
Gene Pool - all alleles within a population
Dominant allele = __ recessive =
P
Q
An example of microevolution is the…
English peppered moth because same species, just changes in population
Hardy Weinberg big 2:
p+q=1 Allelic Frequencies
pp+2pq+qq Genotypic Frequencies
The HW Principle is based on the assumption that the population is:
Not Evolving
What conditions must be met for a population NOT to evolve? (Hypothetically)
- No Mutations
- Random Mating
- No selection
- Large Population
- Isolated Population
